1832, "grass yielding edible grain and cultivated for food," originally an adjective (1818) "having to do with edible grain," from French céréale (16c., "of Ceres;" 18c. in grain sense), from Latin Cerealis "of grain," originally "of Ceres," from Ceres, Italic goddess of agriculture, from PIE *ker-es-, from root *ker- (2) "to grow." The application to breakfast food cereal made from grain is American English, 1899.
also caesium, rare alkaline metal, 1861, coined by Bunsen and Kirchhoff in 1860 in Modern Latin (caesium), from Latin caesius "blue-gray" (especially of eyes), in reference to the two prominent blue lines in its spectrum, by which it was first identified. With metallic element ending -ium. The first metal discovered by the aid of a spectroscope.
umbelliferous European plant long cultivated as food, 1660s, sellery, from French céleri (17c., originally sceleri d'Italie), said by French sources to be from Italian (Lombard dialect) seleri (singular selero), from Late Latin selinon, from Greek selinon "parsley" (in Medieval Greek "celery"), a word of uncertain origin. The c- spelling, attested by 1719 in English, is from French. Middle English words for "wild celery" were acheand selinum.
[O]ne day, in a weak and hungry moment, my roommate and I succumbed to a bit of larceny. A greengrocer's truck had parked down the street and was left unattended. We grabbed the first crate we could off the back. It turned out to be celery. For two days we ate nothing but celery and used up more calories chewing than we realized in energy. "Damn it," I said to my roommate, "What're we going to do? We can't starve." "That's funny," he replied. "I thought we could." [Chuck Jones, "Chuck Amuck," 1989]
late 14c., "pertaining to the sky or the visible heavens; pertaining to the Christian or pagan heaven," from Old French celestial "celestial, heavenly, sky-blue," from Latin caelestis "heavenly, pertaining to the sky," from caelum "heaven, sky; abode of the gods; climate," which is of uncertain origin; perhaps from PIE *kaid-slo-, perhaps from a root also found in Germanic and Baltic meaning "bright, clear" (compare Lithuanian skaidrus "shining, clear;" Old English hador, German heiter "clear, shining, cloudless," Old Norse heið "clear sky").
The Latin word is the source of the usual word for "sky" in most of the Romance languages, such as French ciel, Spanish cielo, Italian cielo, Portuguese céu. Transferred sense of "heavenly, very delightful" in English is from early 15c. Celestial Empire "China" is from 1808, translating native names.
"to perfume with burning incense," late 14c., a shortened form of incense (v.2). Related: Censed; censing.
1887, "a centrifuge machine," originally a machine for separating cream from milk, from French centrifuge, from noun use of adjective meaning "centrifugal" (1801), from Modern Latin centrifugus (see centrifugal). Centrifuge machine is from 1765.
